To all whom it may concern:

Be it known that l, FREDERICK J. HACKER, a citizen of the United Statesof America, and a resident of Waterloo, Biackl-lawk County, Iowa, haveinvented certain new and useful Improvements in Drainage Means forCombination Gutters, of which the following is a specification,

My invention relates to improvements in drainage-means for combinationgutters, and the object of my improvement is to provide means for bothdraining and ventilating the lower troughed member of a combinationgutter which has an impervious lining for and closely spaced from saidlower element.

The invention herein also constitutes an improvement in the constructionof my combination gutter patented September 16, 1919, No. 1,316,301.

This improvement has been eli'ected by the means disclosed in theaccompanying drawing. which is a perspective view of a portion of myimproved combination gutter, showing part of the impervious lining bodyremoved.

The open top longitudinally troughed gutter 1 may be made of any desiredmaterial, although galvanized iron is usually employed for the purposeof economy. To prevent corrosion of the troughed surface of the gutterby moisture or various sedimentary deposits therein a lining strip 7 offlexible waterproof material, such as paper or felt rubberized orimpregnated with bitumen. is placed within and fitted upon the gutter tohave its raised longitudinal edges received in the inverted upper edgeparts 4E and 5 of the gutter, the inverted edge part 5 being bentreversely upward and then outwardly to supply a longitudinally directedstiffening roll 6.

The strip 7 thus constitutes the real receptacle and conduit for water,and thus protects the troughed surface of the gutter 1 from corrosionthereby. The strip 7 being loosely assembled with the gutter 1, there isnecessarily a slight interspace between them whereby when the humidityand temperature of the atmosphere have a certain relation to thetemperature of the gutter 1, the surfaces of the latter will condensemoisture, which eventually causes corrosion by way of the minute cracksthrough the plat- Specification of Letters Patent,

I have provided the following described means to both drain andventilate said interspac-e:

A narrow medial longitudinal trough 2 is formed in the gutter 1 whichreceives, collects and delivers moisture condensed on the V troughsurface of the gutter. To insure a more rapid drainage, a plurality ofsmall holes 3 may be provided in spaced alinement along the drainagetrough 2. The trough 2 may be dispensed with if desired, and merely thedrainage holes 3 employed for said purpose,

The drainage holes 3 are important in that they permit ventilation ofthe interspace between the gutter 1. and the strip 7, that is, air maymove through the interspace by way of said holes, which has the effectoi: measurably preventing condensation of moisture, as also in dryingand carrying oil particles of moisture condensed on the gutter 1.

Other means may be provided for draining and ventilating the interspaceaforesaid without departing from my invention or the scope of itsprotection.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is: Y

1. A longitudinally troughed gutter ele- V ment, and anotherlongitudinally troughed imperforate element positioned therein, thefirst-mentioned element having drainage and ventilating openingspositioned therealong.

2, A longitudinally trougbcd gutter element having a medial longitudinalnarrower 9 trough, and an impervious covering element for saidfirst-mentioned element extending across and spaced from said narrowertrough.

3. A longitudinally troughed gutter element having a medial longitudinalnarrower trough with longitudinally spaced orifices along, and animpervious covering element for said first-mentioned element extendingacross and spaced from said narrower trough, said narrower orificdtrough serving to drain and ventilate the first-mentioned element.
